—Future wireless networks are moving fast towards all-IP network architectures and mobile operators are expanding their services outside traditional cellular networks becoming multi-access operators. This lays stringent requirements on access security, where implementing consistent security policies over disparate radio accesses becomes a challenge. In this(More)
This paper is committed to give an overview of the Host Identity Protocol (HIP), to introduce the basic ideas and the main paradigms behind it, and to make an exhaustive survey of mobility management schemes in the Host Identity Layer. The authors' goal is to show how HIP emerges from the list of potential alternatives with its wild range of possible(More)
The basic idea of QoS is to provide mechanisms that can offer different service levels, which are expressed through well-defined parameters that are specified at run-time on the basis of need. Bit rate, throughput, delay, jitter, and packet loss rate are all examples of common QoS parameters suggested for packet networks. These parameters are all aimed to(More)
—Security is an increasingly important issue for networked services. However, since networked environments may exhibit varying networking behavior and contain heterogeneous devices with varying resources tunable security services are needed. A tunable security service is a service that provides different security configurations that are selected, and(More)
